So, I had this project where I needed to convert a bunch of strings between different casing styles – you know, like camelCase, snake_case, kebab-case, and PascalCase. I thought, “No big deal, should be a quick little task.” Boy, was I wrong. This turned out to be way tougher than I expected!
First Attempts: The Naive Approach
I started by trying to do it all manually with some basic string manipulation. You know, using things like `split()`, `toUpperCase()`, `toLowerCase()`, and a bunch of `if` statements. I figured I could just find the separators (like underscores or hyphens), change the case of the surrounding letters, and be done with it.
It quickly became a tangled mess. I spent an hour wrestling with it, adding more and more conditions to handle edge cases. It was just not working reliably, and I was getting more and more frustrated.
Searching for Existing Solutions
Then I figured, “Okay, surely someone else has already solved this, right?”. I started to searching on the internet.
Sure enough, I found some methods, and it was way better than my initial mess. But, it was still more complicated to use, and didn’t cover all my required cases.
The “Aha!” Moment
After what felt like hours of trial and error,I finally decided write my simple code to achieve the target.
I started by creating an empty string to hold my * use a boolean called `upper_next` to check whether should the next character be uppercase or not.
In that loop,check the characters:
- If it is ‘_’ or ‘-‘,set `upper_next` to `true`,and then `continue`.
- If `upper_next` is `true`,convert the character to uppercase and set `upper_next` to `false`.
- Finally,append the charater to the result string.
The logic finally work!It handled all the different casing styles I threw at it, and it was way more readable than my first *’s my solution to this case tough!
